Windows 7: Rename the DelegateExecute registry value for WMP-associated filetypes

Rename the DelegateExecute registry value for WMP-associated filetypes

To run WMP 12 (32-bit) in multiple instances, I used a hex editor to change the values of 6 consecutive bytes of wmplayer.exe into 90h, starting from 0x823h, as instructed in this PDF.

I succeeded. I ran the patched wmplayer.exe several times, and I got several WMP's on the screen.

But it's still imperfect... because when I clicked on a couple of video/audio files in Windows Explorer, only one instance of WMP would run.

Later I found that if I renamed the registry value DelegateExecute for WMP associated filetypes, multiple video/audeo files could be played simultaneously, each in a WMP instance.

For example, if the DelegateExecute values in the following two registry keys are renamed, then WMP could play AVI files and WMV files seperately in the same time.

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WMP11.AssocFile.AVI\shell\play\command

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WMP11.AssocFile.WMV\shell\play\command

But a question lingers in my mind:"Will renaming DelegateExecute generate any bad things?"

Will it?
